Grimlock ♥ Ultra Magnus

This is going into great detail about how he found the voice for Bee.   It would actually be interesting listening for someone interested in voice acting, I'd think, as it's got some hints and even hints at how others works as well as going into details about how Gilvezan finds the voices.  

He also talks about Optimus Prime's voice and Starscream's voices, and how other voice actor's work.   Fascinating stuff, and I'm not usually into this that much.   (There's even mentions of Homer from the Simpsons, and how that voice has changed.)   

He also talks a little about breaking into the business for the next three or so minutes, and it's captivating me.
